The Millers put in a sterling display in midweek when they crushed League One Notts County in the FA Cup, but Evans is tempted to bring in fresh legs for the game at the Memorial Stadium.
Skipper Ian Sharps and left-back Liam Ridehalgh were unavailable at Meadow Lane due to suspension and ineligibility respectively, but they are now back and targeting a return to the back four.
Mark Bradley and Jack O'Connell performed admirably in their absence on Tuesday so if either of those two missed out at Rovers, it would be harsh.
Evans has also mooted a change of formation from 4-5-1 to 4-4-2, so Courtney Cameron would be the likely beneficiary if the Millers boss went down that route.
Dale Tonge (ankle/knee) made a return to the reserves in midweek but he will not be ready while David Noble (ankle), Lionel Ainsworth (shoulder) and Craig Morgan (foot) are all long-term absentees.
Evans said: "There will be one or two changes, but we will make them for the right reasons, not because they are tired. And the players who are left out might be spewing."
